Application September 15, 1958, Serial No. 761,090

1 Claim. (Cl. 181-60) This invention relates to mufllers for the exhaust gases of combustion engines. An object of the present invention is the provision of a muffier which has two cylinders, namely, an interior cylinder which is immovable and an exterior onewhich is rotated by energy obtained from the exhaust, according to the principle: action--reaction.

The muffler of the present invention is arranged to be used with any type of internal combustion engines when associated with a vehicle or an airplane.

In the accompanying drawings the invention is explained as follows:

Fig. l is a main elevation of the muflier of this invention;

Fig. 2 is a side elevation of the muflier;

Figs. 3, 4 and are transverse sectional views; the sections being taken along the lines 33, 4-4 and 5-5, respectively, of Fig. 2, looking in the direction of the arrows of said lines;

Fig. 6 is a plan view of the muflier of this invention with the outer end portion omitted;

Fig. 7 is a longitudinal sectional view along the line 77 of Fig. 1 looking in the direction of the arrows;

Fig. 8 is a longitudinal sectional view showing the connection of the muffler with one exhaust pipe;

Fig. 9 is a longitudinal sectional view showing the connection of the muffler with two exhaust pipes;

Figs. 10 and 11 are transverse sectional views, the sections being taken along the line. 1010 and 11-11, respectively, of Fig. 8 andFig. 9; looking in the direction of the arrows of said lines.

The muffler shown in the drawings has two cylinders and several supplementary details.

The first cylinder 1 is immovable and at one end the cylinder is closed hermetically while at the other end it has a flange with holes for connection with the wall of the engine surrounding the porthole 10 using bolts 7 connected to combustion engine 8 and four nuts 6.

There are four openings (slots) in the side walls of cylinder 1, as shown in Fig. 4.

The second rotating-cylinder 2 has three openings ring ball bearings 3 and 4. Then the cylinder 2 is locked by lock ring 5.

The cylinder 2 is preferably made of a fire resisting material, such as thin steel, so that it has a minimum weight.

Where the porthole 10 and the flange interfere with the ribs 9 of the combustion engine, the ribs are cut out.

The direction in which the exhaust gases flow and the direction of rotation of cylinder 2 are indicated by arrows in Fig. 4.

The arrangement for connecting the mufiler of the present invention with exhaust piles is shown in Figures 8-11 of the drawings.

The connection of the muffler with one exhaust pipe 12 is shown on Figs. 8 and 10. In this case slits 15 are made in the end of cylinder 1 for tight connection with exhaust pipe 12, when using clamps 11, 13, 14.

Another case, when the mufller is connected with two exhaust pipes 12, as shown on Figures 9 and 11; slits 16 are made in the ends of exhaust pipes 12. For tight connection the same clamps 11, 13, 14 are used.

I claim:

A mufller, comprising, in combination, an inner immovable cylinder having a closed outer end and an open inner end, a flange enclosing said open inner end and having engine-connecting portions, said cylinder having a plurality of spaced slots extending in the longitudinal direction thereof, the interior of said cylinder being empty to provide unrestricted passage for exhaust gases, two rings of ball bearings mounted upon said cylinder at opposite ends thereof, another rotary cylinder carried by said ball bearings and enclosing the first-mentioned cylinder, said other cylinder having a plurality of spaced slots extending in the longitudinal direction thereof, and an equal number of raised portions extending in the same circumferential direction above the last-mentioned slots, each of said raised portions extending above a separate slot and above an adjacent surface portion of said other cylinder parallel to the circumference thereof, and having a closed curved end constituting a continuation of an edge of the slot, and an open end for the discharge of the exhaust gases.
